Things to do while working on the gearbox?
Posted: Tue Sep 16, 2014 7:51 am
Hello,
During last rally, the gearbox from my 1972 Elan Sprint started to make a whinning noise when in 1st, 2nd and 3rd gears only.
No weird sound in 4th. No weird sound if you press the clutch pedal while driving. No problem at all for changing gears up or down. Only this hissing sound.....which was not there 2 days ago.
I have been told by Alexblack and Rohan and others that the bearings were involved. that the casing should be also checked in order to see if the loose bearings have not eaten the casing with the vibration.
This is a too heavy and scary work for me to perform in house with my two left hands.
So this means to me taking my car to a french garage that will force me to sell one kidney or an eye I don't know yet
This involves I guess : Taking the engine out, Taking the gearbox out, probably taking apart the gearbox to replace these damn bearings.
So... hence the high labour costs, may be there are things to do that I will be able to do once for good and don't come back.
Please help me to list them to see if it is interesting to group some mechanical upgrades or preventive maintenance to perform while everything out of the car :
- Should I change the gear ratios? Are the sprint ratios of my 2000E gearbox known to be unadequate and that another ratio is much more suitable? I want to stay synchro and not Dog engagement. A exhaustive list of ratios is there but I admit it is chinese for me. Have a look http://www.daveraemotorsport.com/ford-gearkits.html
- Should I change the current clutch and purchase a new one to be on the safe side?
- Would it be an ideal time to put a Fast road TTR or Keveldon Manifold, remove the studs and use classic bolts instead?
.....thank you for your help.
